Mailsuite Review 2026: Pricing, Pros, Cons, and Whether It's Worth It
You just installed Mailsuite, tracked your first email, and got a satisfying little notification when your prospect opened it. Then you hit the 10-email limit. Now you're wondering whether $11.99/month is worth it - or whether you should look elsewhere entirely.
The 30-second verdict: Mailsuite (formerly Mailtrack) is a solid free email tracker for Gmail if you send a handful of tracked emails per day. But the free plan's 10-email cap makes it a demo, not a tool. The Advanced plan at $11.99/user/month is reasonable for solo users who live in Gmail, but it's hard to justify for sales teams. If you need CRM integrations, sequences, or verified contact data, Mailsuite isn't the answer.
Pricing Breakdown
Mailsuite keeps it simple - two tiers on their official pricing page: Free and Advanced. The simplicity is misleading, though.
Third-party sources still reference a Pro tier at EUR 2.99/month and an Advanced tier at EUR 5.99/month that aren't shown in the current pricing-page structure. GetApp shows a starting price of $9.99/user/month, not $11.99. The pricing has clearly shifted over time, which feeds into the billing complaints we'll get to.
Here's what the pricing page shows today:
| Feature | Free ($0/mo) | Advanced ($11.99/user/mo) |
|---|---|---|
| Open tracking | 10 emails | Unlimited |
| Link clicks | 10 emails | Unlimited |
| Campaigns | 100/mo | 60,000/mo |
| PDF tracking | 5 docs | Unlimited |
| E-sign | 5 docs | Unlimited |
| Screen recordings | 5 videos | Unlimited |
| Reports | Daily only | Weekly + Monthly |
| Mailsuite branding | Shown | Removed |
Team discounts exist: 18% off at 5+ seats, 25% at 10+, 35% at 50+. The pricing page also includes a modal warning that says "Sorry, you can't downgrade to a lower plan than what you have currently." That's an unusual policy, and it's generated real frustration among users.
What Users Actually Like
Mailsuite sits at 4.6/5 from 134 reviews on G2, with 76% giving it five stars. GetApp tells a similar story at 4.5/5 from 227 reviews.
The praise is consistent and narrow. Users love the dead-simple setup - in our testing, the Chrome extension installed in under 30 seconds and we were tracking emails within a minute. Real-time open notifications are the killer feature. For freelancers and solopreneurs who just want to know if a client read their proposal, it does the job well.
The Real Cons
Here's where things get interesting. Mailsuite's Trustpilot score is 2.7/5 from 283 reviews - a massive gap from that 4.6 on G2. We've seen this pattern before with other tools, and it almost always signals billing friction. G2 captures the first-week experience: easy setup, cool notifications. Trustpilot captures month three: billing surprises, feature gating, and radio silence from support.
The recurring themes on Trustpilot are hard to ignore. Users describe price increases from $9.99 to $19.99 with the cheaper monthly option disappearing. Others describe being forced to enable a bulk feature they didn't want, with concerns it would trigger a higher subscription tier - one reviewer called it feeling "hijacked." Multiple users had to go through PayPal to get refunds because support didn't respond. Trustpilot also shows the company profile "Hasn't replied to negative reviews," which isn't a great look.
Beyond billing, there are platform limitations. Mailsuite is primarily a Chrome + Gmail workflow, and Outlook support is still described as beta in several sources. Reddit threads on r/email flag accuracy concerns - opens and clicks sometimes appear clustered in ways that don't make sense, like multiple link clicks within a single minute. Users also report browser slowdowns.
Then there's the privacy angle that nobody talks about. Mailsuite acts as a data processor under GDPR, but the tracking pixel fires without recipient consent. Recipients can block it by disabling automatic image loading, but users on r/privacy have flagged Mailsuite's opt-out notification as so confusingly worded that one thread questioned whether it was a phishing attempt. If you're emailing prospects in the EU, that's worth thinking about.
Mailsuite tells you someone opened your email. Prospeo makes sure you're emailing the right person in the first place. With 300M+ profiles, 98% email accuracy, and a 7-day data refresh cycle, your outbound actually connects.
75 free verified emails per month. No credit card. No billing surprises.
Reviews at a Glance
| Platform | Rating | Reviews |
|---|---|---|
| G2 | 4.6/5 | 134 |
| GetApp | 4.5/5 | 227 |
| Trustpilot | 2.7/5 | 283 |
G2 captures the honeymoon. Trustpilot captures the breakup.
Who Should Use It (and Who Shouldn't)
Use Mailsuite if:
- You're a freelancer or solopreneur on Gmail
- You send fewer than 10 tracked emails per day
- You want free open notifications
- You don't need anything beyond basic tracking
Skip it if:
- You need Outlook support or team-wide dashboards
- You need CRM integration or email sequences
- You need verified contact data for outbound prospecting
- Your bottleneck is finding the right emails, not tracking opens
Let's be honest: most people evaluating Mailsuite's paid plan are trying to solve the wrong problem. Knowing someone opened your email is a vanity metric if you aren't sure you're reaching the right person. For outbound teams, the money is better spent on data quality than open tracking.
If you're building a repeatable outbound motion, it also helps to standardize your sales prospecting techniques and tighten your email deliverability before you obsess over opens.
Alternatives Worth Considering
Prospeo solves the problem many Mailsuite evaluators actually need to solve. Its database covers 300M+ professional profiles with 98% email accuracy and a 7-day data refresh cycle. The free tier gives you 75 verified emails and 100 Chrome extension credits per month, with paid plans starting at roughly $0.01/email. For outbound teams, pairing verified contact data with any sequencer will book more meetings than knowing someone opened your email.
Yesware is the natural step up for sales reps who've outgrown a simple tracker. It supports both Gmail and Outlook, integrates with Salesforce, and includes templates and campaigns. Pro starts at $15/seat/month on annual billing. One catch: on Free and Pro tiers, tracking only works for emails sent in the last 24 hours. That lookback limitation matters if you're tracking proposals with long decision cycles.
If you're comparing tools in this category, you may also want to look at follow up email software and broader SDR tools that include sequencing and reporting.
Mixmax costs $89/user/month on annual billing - a completely different category. It's a full sales engagement platform with sequences, scheduling, AI copilots, and a dialer. Way more than you need for simple tracking, but if you're building a proper outbound motion, it's worth evaluating. The distinction matters: Mailsuite is a Gmail tracking plugin, while tools like Mixmax are cold email infrastructure. Know which one you actually need before you buy.
If you go down the engagement-platform route, it’s worth understanding sequence management and how to connect outreach tool to CRM so tracking and attribution don’t break.
You're evaluating $11.99/month for open tracking - but your real bottleneck isn't knowing who opened. It's reaching decision-makers with valid emails. Prospeo delivers verified B2B emails at ~$0.01 each with 98% accuracy, so every send counts.
Spend less than Mailsuite Advanced and get data that actually books meetings.
The Bottom Line
Mailsuite Free is fine for casual Gmail tracking - just know you're getting a taste, not a tool. The pattern across Mailsuite's pricing, reviews, pros and cons is clear: great for lightweight personal use, risky for anything more. Don't pay $11.99/month unless you specifically need unlimited tracking and campaign sending from Gmail.
For sales teams doing real outbound, invest in data quality or a full engagement platform. The open rate on your cold email matters a lot less than whether you're reaching the right inbox in the first place. If you want to go deeper on tracking mechanics, see our guide to the email tracking pixel.
